CONCRETE WALLS arm rim LIKE.

Patented Feb. 4, 1908.

Application filed Au st 4, 1906-- Serial No. 329-151 and State of New York, have invented a new and useful Improvement in Means for Use in Buildin which t e following is a specification.

The object of my presentinvention is to provide an improved means for use in building concrete walls and the like whereby a vertical face for the wall may be insured by the use of a comparatively small number of trusses at atime; the construction of the trusses being such that they may be readily shifted for each succeeding layer of concrete.

In the accompanying drawings, Figure 1 shows one of the trusses in full lines having its lower portion secured to the top layer of a concrete wall or foundation, the series of bolts which are to be embedded in the next succeeding layer being shown attached to the up er portion of the truss and the position of the truss for the third layer being shown-in broken lines, Fig. 2 is an outside elevation of two adjacent trusses, and'Fig. 3 is an inside elevation of two adjacent trusses.

The upper layer of the concrete wall or foundation is denoted by 1. To the face 2 of this wall or foundation is secured a plurality of trusses. Each truss comprises a vertical beam 3, upper and. lower laterally extended planks 4, 5, laterally arranged diagonal braces 6, 7, and vertically arranged diagonal braces 8, '9. A centrally arranged bolt 10 extends from the beam 3 outwardly and passes through the meeting ends of the lateral and vertical diagonal braces 6', 7, 8, 9, said bolt being plro'vided with a nut 11 arranged to bring t e proper strain on the truss for strengthening the beam 3..

Each of the braces and the beam 3 may be constructed of a plurality of pieces rigidly secured together, as shown, if so desired.

The laterally extended planks 4 and 5 are arranged to engage the face of the wall with the top of the upper laterally extended plank 4 substantially in alinement with the top of the upper layer of concrete.

The lower ortion of the trussis removably engaged Wit a series of bolts '12, 13, 14,

Concrete Walls and the Like, of

which have been embedded in the concrete wall by causing the ends of the said bolts 12, 13, 14, to extend through the vertical beam'3 and providing the ends of the said bolts with removable nuts 15, 16, 17, engaging the outer face of the said beam.

The upper portion of the truss has removably attached thereto a series 'of bolts 12*,

13*, 14*, corresponding to the lower series of bolts 12, 13, 14, the upper series of bolts 12*,

13*, 14*, being arranged-in position to be embedded in the next succeeding layer of concrete. which the bolts 12*, 13*, 14*, are embedded, has set, each truss will be removed from the upper and lower series of bolts by removing the nuts 15*, 16*, 17*, 15, 16, 17. Each truss will then be moved upwardly a step so that its lower portion will be caused to engage the upper series of bolts 12*, 13,* 14*.

After the layer of concrete in A new series of bolts is then removably placed in position in ,the upper portion of each truss ready to be embedded in the succeeding layer of concrete.

From the above description it will be seen that instead of providing atrussed framework of the height of the wall-to be built, a series of individual trusses arranged side by side may be utilized,eachtruss bein only of a sufficient height to guide the builders in the formation of the next succeeding layer. Furthermore, the trusses can be more easily handled and are more accurate than larger trusses and the trusses may be used over and over again, the trusses only having to be supplied with new fastening bolts as required.

It is to be understood in use that the trusses are secured together side by side with ,the ends of the upper and lower laterally extended planks 4, 5, in engagement with each other. These planks space the vertical beam 3 from the face 2 of the completed concrete layer thus leaving room for facin planks to be inserted along the inner side or the upper portion of the beam 3 for retaining the next succeeding lay er of concrete in position.
